@@ -62,7 +62,7 @@ All tests support the same set of arguments :
* `-a,--average <0/1/2/3>` Report performance as an average across all ranks (MPI=1 only). <0=Rank0,1=Avg,2=Min,3=Max>. Default : 1.
* Test operation
* `-p,--parallel_init <0/1>` use threads to initialize NCCL in parallel. Default : 0.
* `-c,--check <0/1>` check correctness of results. This can be quite slow on large numbers of GPUs. Default : 1.
* `-c,--check <check iteration count>` perform count iterations, checking correctness of results on each iteration. This can be quite slow on large numbers of GPUs. Default : 1.
* `-z,--blocking <0/1>` Make NCCL collective blocking, i.e. have CPUs wait and sync after each collective. Default : 0.
* `-G,--cudagraph <num graph launches>` Capture iterations as a CUDA graph and then replay specified number of times. Default : 0.
